Fructose has no impact on weight gain, says a team of Canadian researchers which recently concluded that it is yet not cited or concluded whether or not there is any connection between fructose and weight gain from any of the studies ran till date.

Researchers have cleared in their statements that Fructose has no excessive contribution in gaining weight than any other types of carbohydrate. Above statements from the researchers have been reported in the Annals of Internal Medicine.

During their studies, the researchers, upon adding any extra fructose to the foods, noticed no trigger to the weight gain but it remained unaffected only until the participants did not reduce equivalent total calories from other carbohydrates saying that fructose calories are not at all more fattening than equivalent calories of other carbohydrate foods.

According to the authors, it is a common belief in Western societies that fructose contributes to excess bodyweight, but that is not true as no studies have yet given any such results to prove the connection.

To make people understand briefly about fructose, John L. Sievenpiper and his team set out some studies to clearly show people what effect fructose has on people's weight if it is eaten in control.

To gather firm results, the researchers collected data of 41 controlled feeding trials which were ran for at least seven days. Out of 41, around 31 reports (of approximately 637 participants) were studied to compare the effect of free fructose and non-fructose carbohydrates in iso-caloric trials, i. e. ones with equivalent total calories. Also, the other 10 studies, which involved 119 participants, were done on hyper-caloric trials, i. e. high calories.

Researchers noted no change or gain in body weight from fructose in the iso-caloric trials as compared to non-fructose carbohydrates. But yes, high calorie fructose diets did showed increases in body weight.
